Authorities in Serbia say they have banned 120 people from traveling to Bosnia to take part in parallel rallies this weekend of opposing Bosnian Serb political camps.

Interior Minister Nebojsa Stefanovic said Friday the aim was to minimize the possibility of incidents Saturday in the town of Banja Luka, where an opposition alliance and the Bosnian Serb government are both holding rallies. Serbia's Prime Minister Aleksandar Vucic has warned of possible violence.

Stefanovic says authorities in Serbia "will do all we can so that nothing happens tomorrow." He adds that "we won't get involved in politics, but we want peace."

Any violence in Bosnia is potentially explosive, following the 1992-95 war there that claimed some 100,000 lives.
